Here's a "trivia" instead of the "SFW Section", about what I found in Blanc Kisaragi's request: according to Pixiv's dictionary, a "OneDraw" refers to a challenge in which the artist is asked to draw something within one hour (or "60 minutes", whatever you want). "OD" images are, then of course, done within that span.The idea behind it is to test how much one can draw within a short time.

"Random SFW Section: Chap.39"I used Pixiv's "Discovery" function again.I just ran out of ideas, and that thing shouldn't be able to help much more given how it works, yet I still get some interesting images from there.
